Which of the following materials is the most dominant in aero engine applications?
View Answer Explanation
Melting and casting of titanium are very difficult due to its high chemical reactivity with mould materials.
In general, titanium castings exhibits excellent fatigue strength due to its high rigidity.
Refractory oxides do not have any effect on molten titanium metal at the time of casting process.
Which of the following methods of melting is not used for melting titanium metal?
Titanium metal generally has a high melting point and low thermal conductivity.
How is much amount of chromium (in percent) normally added in steel to be called as stainless steel?
Which of the following types of stainless steels contain maximum amount of chromium in it?
In the manufacturing of stainless steel, oxidation of carbon and chromium cannot be possible.
Which of the following materials is required in a technique of decarburizing the molten steel?
In argon oxygen decarburization (AOD) method, whole process is carried out in a converter type of vessel.
